yeah man it totally is. You can even see in the pictures i took where the bolts holding the guibo hit the sides of it, causing the vibration. my buddy pointed thaty out last night over a bottle of vodka.
im just gonna see if i can steal one from a junkyard, but i dont think one off a e30 will work, so ill have to findd a junkyard with e36 which is quite hard in this city.
